HOSE-SUPPORT.

SPECIFICATION forming part of Letters Patent No. 484,557, dated October18, 1892.

Application filed June 10, 1892. Serial No. 436,239. (No model.)

, the blockading of streets adjacent to a fire.

Many devices have heretofore been suggested for this purpose, but ofsuch a construction as were prohibitive of their adoption. These priordevices were constructed in the form of a sectional bridge providedalong the ridge with a series of rigid forks for the reception of a lineof hose. As one of these structures is required for each line of hoseand as they are so complicated and heavy, it is necessary to employ alarge number of men to erect them within any reasonable limits of time,

and, further, as the hose had to be placed in position on the bridgeafter the latter was erected and as the use of the hose could not bedelayed until the bridge was ready for use the labor required to placethe hose on the bridge was very great.

The object of the present invention is to provide a series ofindependent supports for the hose, constructed to take such a firm holdon the hose that the latter will serve in part to hold the support in avertical position, and also adapted to be carried upon cars whosemovements are stopped by the line of hose.

In general terms the invention consists in the construction andcombination, substantially as hereinafter more fully described andclaimed.

In the accompanying drawings, forming a part of this specification,Figure l is a view in elevation showing aline of hose supported by mydevice over street-car lines. Fig. 2 is a sectional view showing thepreferred form of spring-jaws. Fig. 3 is a similar view taken at rightangles to Fig. 2. Fig. 4 is a plan view of the socket on an enlargedscale. Fig. 5 is a perspective view showing the manner of arranging thesupporting-poles, and Fig. 6 is an elvation showing a modification inthe construction of jaws.

In the practice of my invention a pair of spring-jaws 2 is secured onthe upper end of a pole 1, of sufficient length to raise a line of hoseso as to permit of the passage of streetcars thereunder. The jaws havetheir inner faces formed in a curve having a radius approximately equalto the radius of the curvature of the outer wall of the hose to beraised, so that said jaws will take a firm grip on the hose. It ispreferred that the jaws shall grip the hose so tightly that the latterwill when expanded by water swell out slightly on each side of the jawsand thereby prevent any movement of the jaws along the hose. The jawsmay be formed integral-with the socket 3 and be immovable, except fortheir resilient outer movement when forced into the hose, as shown inFigs. 5 and 6. It is preferred, however, to form the jaws on the upperends of shanks 4, adapted to fit in the socket 3, which is secured tothe upper end of the pole 1. The shanks are held projecting from thesocket by a spring 5, on which the lower ends of the shanks rest. Theshanks are prevented from being forced out of the socket by a pin 6,passing through holes in the socket and slots 7 in the shanks, the slotspermitting of the full movement of the jaws and shanks. As shown in Fig.l,the socket is bell-mouthed at its upper end, so as to permit of theseparation of the jaws when raised by the spring, and the faces of theshanks are inclined, so that the jaws will be forced together by thesocket when the shanks are pressed inward by the weight of the hose.

In order to open the jaws when the shanks are moved outward by thespring 5, notches having inclined walls 8 are formed on the inner facesof the shanks. As the. shanks are moved outwardly these inclined walls 8bear upon a pin 9, passing through the socket, and force the jaws, so asto be in position to be placed on a line of hose.

In using my improvement it is intended that four or six poles having myspring-jaws attached should be carried in a suitable rack 10 on top ofthe cars, as shown in Fig. 1. As soon as a car reaches a line of hoseacross its track the driver and conductor take two of the poles andapply the jaws to the hose from opposite sides. Then by pushing up andagainst each other, the lower ends of the poles being carried in towardeach other, aportion of the hose can be quickly raised. As soon as thepoles have been applied and the hose raised on one side of the track theother poles are applied to the hose at such point that when the latteris raised the two pairs of supporting-poles will be on opposite sides ofthe track. If two or more lines of hose are laid across the tracks thepoles on the next car are brought forward until all the lines of hoseare raised. As soon as the line of hose is raised over one track it canbe raised over the parallel track by a pair of poles from a car on saidtrack.

As hereinbefore stated, the jaws are made of such a size relative to thesize of the hose that they will take a firm hold on the hose, so as notto slip along it. While it is preferred to so arrange the outside pairsof poles that their upper ends will incline outwardly from the track theweight of hose and the portion 1ying on the ground on each side of thetracks will act as guys and prevent the poles falling over.

I claim herein as my invention- 1. Ahose-support having,in combination,a pole and a pair of spring-jaws constructed to take such a grasp on thehose as will prevent a movement of the jaws along the hose,substantially as set forth.

2. A hose-support, havingin combination, a

pole provided with a socket, jaws provided with shanks fitting in saidsocket, and a spring for forcing the shanks outward to permit of theopening of the jaws, substantially as set forth.

3. Ahose-supporthaving, in c0mbination,a pole provided withabell-mouthed socket,jaws provided with shanks having inclined outerfaces and provided with inclined walls on their inner faces, a springfor forcing the shanks outwardly, and a pin operative on the inclinedwalls for spreading the jaws apart on the outward movement of the shanksand jaws, sub stantially as set forth.

In testimony whereof I have hereunto set my hand.
